American Eagle song

I heard this song a while ago in AE, then again at the Mac counter in Macy's some month's later. The song sounds like the guy is saying "think i'm in love with you" or some variation of that, and he repeats "i'm not" throughout the song. The music video is like a cut-out style cartoon with two circle things that fall down waterfalls and stuff then meet up at the end and are happy. It's been stuck in my head since the first time I saw it and I have got to find out what it is!

no one has found it yet? i'll try to give more info to help

the chorus had the guy singing "wa wa wa wa wa wa wa wa wa wa wa" (or maybe la la, but it sounded like a w). the sound was almost like modest mouse but a bit more uptempo

i've been trying to find this one too it's driving me nuts!!!! anyone know?
